Enum rustc_infer::infer::region_constraints::UndoLog[−][src]

pub(crate) enum UndoLog<'tcx> {
    AddVar(RegionVid),
    AddConstraint(Constraint<'tcx>),
    AddVerify(usize),
    AddGiven(Region<'tcx>, RegionVid),

}

Variants

AddVar(RegionVid)

We added RegionVid.

AddConstraint(Constraint<'tcx>)

We added the given constraint.

AddVerify(usize)

We added the given verify.

AddGiven(Region<'tcx>, RegionVid)

We added the given given.

AddCombination(CombineMapType, TwoRegions<'tcx>)

We added a GLB/LUB “combination variable”.

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
